Double-layer interchange type fishway structure
The invention discloses a double-layer interchange type fishway structure, and belongs to the field of fishway design in water conservancy projects. Through the double-layer interchange type design, upper-layer overflow and lower-layer submerged flow can be achieved, the water flow structure in the pond is rich, the pond can adapt to different water depths, and good hydraulic conditions are created for fishes with different favors. The double-layer interchange type fishway comprises a horn-shaped inlet section, a hump weir-shaped transition section, a double-layer interchange pool chamber section (comprising a lower-layer disc-shaped channel section and an upper-layer overflow section) and a rest pool chamber section. The hump weir section can divide the pond chamber into an upper-layer overflow area and a lower-layer submerging outflow area, the formation of the upper-layer overflow area introduces fishes loving to jump into the upper-layer overflow weir section, and the lower-layer submerging outflow area is used for attracting fishes loving to inhabit at the bottom layer and smoothly upstream through the disc-shaped channel section; the arrangement of the rest pool chamber section can form a low-flow-velocity area to restore the physical strength of the fishes, so that the fishes can smoothly complete upstream tracing, and the stability of a river ecological system is ensured.
本发明公开一种双层立交式鱼道结构，属于水利工程中鱼道设计领域。通过双层立交式设计能够实现上层溢流下层淹没流，池室内水流结构丰富，能够适应不同水深，为不同喜好鱼类创造良好水力条件。所述双层立交式鱼道包括：喇叭形进口段、驼峰堰形过渡段、双层立交池室段（包括下层圆盘形渠道段、上层溢流段）和休息池室段组成。驼峰堰段能则将池室分为上层溢流区及下层淹没出流区，上层溢流区的形成将喜跳跃的鱼类引入上层溢流堰段，而下层淹没流区用于吸引喜底层栖息的鱼类并通过圆盘形渠道段顺利上溯；休息池室段的布置能够形成低流速区使鱼类体力恢复，从而使鱼类顺利完成上溯，保证了河流生态系统的稳定。
